This is my site. I choose not to have comments. I recognise that sometimes people feel the need to respond to what I write here, and I love that. Please do it on your own site. Or Twitter. Or Facebook. Or Google+. Or send me an email (actually, please don't do that). Or any of the other hundred+ ways to communicate on the Internet.
It's the getting of your own site that's the deal breaker here. Which is why the larger platforms are winning out and the web seemingly being enveloped into the Twitter / Facebook / Google black hole.
